Specification of Lettere Patent. Patented JillllM-B Ill, ll1.

Application filed December 8, 1915. Serial Ito. eases.

To all whom it may concern:

Be itknown that I, FRANCIS Ci, MASON, a citizen of the United States, residing at Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Vacuum-Cleaners, of which the following is a specification.

This invention relates to an improved vacuum cleaner and particularly those which have a rotary brush in the nozzle thereof.

This invention is closely related to the concurrent application filed herewith, and in addition to the objects of the concurrent application has for its objects an improved arrangement and modification of the gears of the driving wheels and of the connections thereof to the adjusting eccentrics.

Further objects, and objects relating todetails and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention 'by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 'I is a perspective view of my improved vacuum cleaner with the fan and motor removed.

Fig. II is a transverse vertical section with the motor removed, taken on a line corresponding to the section line 2-2 of Fig. IH.

Fig. III is an inverted plan view of the suction nozzle of my improved cleaner with the brush in place, the remainder of the machine broken away.

Fig. IV is an enlar ed detail vertical section showing the adjustment and driving mechanism of the brush roll, taken on the section line 44 of Figs. I, IIIand VII.

Fig. V is an enlarged detail vertical section through the driving wheel showing the arrangement of the gears therein, taken on a line corresponding to section line 5-5 of Fig. IV.

Fig. V1 is an enlarged detail vertical section showing the connection of the adjustin eccentric to the gear plate.

Fig. VII is an an detail vertical in the end wall thereof, taken on aline correspondin to the section line 7-7 of Figs. III and I Fig. VIII is an enlarged detail vertical section showing the mounting of the carrying wheel, taken on a line corresponding to section through one end of the nozzle show- 7 ing the position of the adjusting eccentric the broken section line 8-8 of Figs. III

several views, and the sectional views are taken looking in the directipn of the little arrows at the ends of the section lines.

Referring to the drawings, I consider the themselves, in which the vacuum cleaner reference characters representing the parts casing or housing consists of a nozzle 1,

a fan chamber 2 in which revolves thesuc:

tion fan 3 driven by a motor, not shown herein, but mounted on the wall 4 of said fan chamber.

The fan chamber 2 is connected to the nozzle 1 by the suction passage 5 and discharges through the discharge passage 6 formed by the discharge nozzle 7, w ich connects to a dust bag or other collector, not herein shown. chamber walls is the handle bail 11. The whole machine runs on the driving wheel 8 and the carrying wheel 9 situated in nozzle 1 and a single rear trailing caster 10 partially shown in Fig. II.

Between the two front wheels Sand 9 and carried by them is the rotary brush 12. Both of the wheels 8. and 9 are carried in journal bearings in adjusting eccentrics 13 and 14, respectively. These adjusting eccentrics are loosely mounted in the end walls of the nozzle -1 and are held in place by shaped adjusting handle 15, said handle being screw fastened to the adjusting eccentrics, as shown. I

Pivotally mounted within adjusting ecis the brush roll shaft '16. The main driving wheel 8 is comprised of the two wheels 17 and 18 securely riveted together. On an enlarged portion 19 of sa d brush roll On the side of the fan the bailare centric 13 and ofiset from the center thereof I shaft 16 the driving wheel 8 freely turns,

said portion 19 being securely pinned. to the brush roll 12 by the pin 20. The outer face of driving wheel 8 is closed by a cover 21, thus forming an annular chamber with the central web of the wheel. Securely set in cover 21 is a plurality of pinion studs 22 on which turn'the pinions 23.. On the in- The other end of thebrush rollturns on the shaft 27 securely held in eccentric 1d supporting wheel 9 freely turning on said shaft 27. Therefore, when driving wheel 8 is rotated annular gear 241 rotates the pinions 23 and these in turn drive the brush roll driven gear 25, thereby turning the brush roll. Both wheels have on their peripheries suitable friction treads.

Sepured to top of nozzle 1 is the curved notched setting plate 28, for adjusting bail handle 15, the notches of which are adapted to engage the longitudinal portion of said handle 15. The curve of said settin plate is on a constantly increasin. radius, thereby retaining the setting hand e in a sprung position, securely holding the same at a given notch.

Therefore when the adjusting eccentrics are turned to various positions by bail 15,

the eccentrically set driving wheel will ad-' just the nozzle to various heights above the article cleaned, suction slot 29 being wide enough to take care of the horizontal component of such adjustment.

1 have claimed the invention herein broadly in a companion application Serial No, 653 17, filed December 6, 1915, and here incense 1. In a combined vacuum cleaner and carpet sweeper, the combination of a nozzle casing, suction creating means connected therewith, a retail" carpet sweeper brush supported within t e nozzle casing, an eccentric adjusting means mounted on the ends of the brush and rotatably mounted in the ends of saidcasing, door wheels at the ends of said carpet sweeper brush, a multiplying gearing disposed within one of said floor wheels comprising an internal spur V ear secured to said wheel, a circular plate fixed to the adjusting means, spur gear pinions on journal pins on said fixed plate meshing with the said internal gear, a driven spur gear secured to said brush and disposed between the said pinions and in mesh therewith to be driven thereby, coactin for the purpose specified.

2. n a carpet sweeper structure, a retary carpetsweeper brush in a suitable casing, floor wheels at the ends ot said carpet sweeper brush, eccentric adjusting means mounted in the ends of said casing,a multiplying gearing disposed within one of said floor wheels comprising an internal spur gear secured to said wheel, a circular plate fixed to one of said adjusting means, spur gear pinions on journal pins on said lined plate meshing with the said internal gear, a driven spur gear secured to drive said brush and disposed between the said pinions and in mesh therewith to be driven thereby, coactingicor the purpose specified.

1n witness whereof, T have hereunto set in hand and seal in the presence of two witnesses. v
